Many labs prefer autofill cryogenic storage systems for the obvious ease of operation, but here’s another reason to love the Thermo Cryo Plus 4: it’s so large that for a lot of labs it’s the only cryogenic storage solution you’ll need.

What’s that you say? You have tens of thousands of samples in 2mL vials, so there’s no way the Cryo Plus 4 could possibly fit all the tissue culture samples your lab stores on a regular basis? Well, with a capacity of 38,5000 vials we think it can at least come close. This cryo storage system has a massive 552L capacity, a static evaporation rate of only 10L per day and static holding time of 55days, the Cryo Plus 4 can not only fit all your samples but also safely store them without power or LN2 refill for almost two months.
Set up for the Cryo Plus 4 is relatively straightforward. Simply wheel the tank into place next to the liquid nitrogen supply and use the transfer hose to connect the Cryo Plus 4 to the supply, making sure that the supply is low pressure regulated to 22PSIG or less. Once the transfer hose is connected, open the supply tank valve and check the connections for leaks. As with any LN2 system make sure this unit is kept in a well-ventilated are of the laboratory. Then simply turn on the power switch and begin filling the tank chamber and watch the bar graph on the front of the unit display the liquid level. Key features include audible and visual alarm combinations, a liquid level sensor, a top mounted control panel for easy visibility and programming, and a digital temp display sensor under the lid.
We test all our cryopreservation systems prior to shipment using LN2. Our technicians measure static evaporation rate and holding time of the tanks, as well as level monitoring apparatus and autofill control systems.
